I currently ride an 04 WR 450 and I LOVE the bike but I ride in the Mojave and it doesnt handle the high speed whoops as well as I would like. Sure I could get the suspension professionally done and then it would handle them but that would cost upwards of $600ish. In my mind I think putting that money towards a newer bike would be the smarter move. Im looking at a like new 06 WR 450 and my question is will it handle the whoops better? From the reseach I have found it seems that Yamaha made a pretty big jump from the 04's to the 05's making them lighter, narrower and huge upgrades to suspension. Anyone have some thoughts??... PS if I end up making the jump from my 04 to the 06 then the 04 will be up for sale at a DANG good price!
